Honeybees Love The Small Dahlias. 20 Aug 24.

 These were the seed - started Mignon dahlias.  About 18 inches tall.


Each flower has one to three honeybees.  The other seed started dahlias have  been bee - friendly too. 

I put a label on each, hoping to keep track of them, dig up the tubers and overwinter this winter / fall.

 These were overwintered from last year.  




Pink Mandevilla Update. Thrived After Rehab. 20 Aug 24.

 This is the two- or three- year old Mandevilla vine that I overwintered.  In April, I pruned severely and repotted in fresh potting soil.   info 20 Apr 24.

It took a while for full comeback.  That was a severe rehab.  Here it is now.


Pretty dramatic comeback.

I can't recall what I did previous years.  This time I used a dilute balanced fertilizer until it leafed out, then occasional dilute bloom food.  No high nitrogen - I don't want long vines this time. 



Late Summer Cuttings. Geranium, Spanish Lavender, Sage, Rosemary. 20 Aug 24.

 There are several plants in the border that I think I'd like to propagate for planting next Spring.  If they root, I can keep them in  sheltered location or in the Sunroom during cold winter weather.

I tried sage, Rosemary, and geraniums in water over the past few weeks.  Not doing well, which might be the season or other factors.  Sometimes it works for me for geraniums.  I've seen on line that water works for rosemary and sage.  One geranium cutting grew a root and is in soil now.

I didn't have more sage, so trimmed the cuttings in water back to fresh tissue.   I did that for the rosemary too.

My cutting materials before trimming.


With the sage, I want fresh clean cuts in fresh tissue.  Also, the leaves might transpire too much, so I trimmed them.

Sage cutting, before trimming.  I used single edge razor blade for the sharpest, cleanest cuts.



After trimming.  I want fresh, healthy cambium tissue, clean with no long term water effect, so the rooting hormone soaks in better.


Then I used a butter knife as a dibbler, made a hole in pre-wetted seed starting medium, and inserted about two nodes deep.

Cleanup of the rosemary cuttings was similar.  Before and after trimming, same photo.


I also cut the apical growth.  I don't know if that makes a difference.

After trimming.



Treatment of Spanish lavender cuttings was similar to the rosemary, except they were freshly harvested.

All planted.


Then I placed the pots of cuttings into produce bags.  Four fit per bag.


I'm keeping them on the North side of the garden shed, out of the sun,  Current temp is 70F.

Will they root and grow?  I'll be watching them.

Extreme Pruning of Lavender Bush. 15 Aug 24.

 Still doing rehab of the border.

When I first planted the border, I moved some lavender plants there that had been in a wildflower meadow.  I don't know the cultivar.  They survived and grew, but during the past two years I was unable to care for the border.  It was taken over, mainly by thistles.

Two of those lavender plants survived but were so scraggly and woody, I didn't think they could be rehabilitated.  So I cut them off.

That was a week ago.  Today I noticed there were multiple buds growing from the bases.





Will they survive?  I don't know.  All of the web info I could find, says they can't cone back if cut down to old wood.  Maybe they will grow.   I mulched around them and gave some diluted fertilizer.  They still have about three months to grow, before frost.
